Guys,

I have created a filter from FDAtool and want to test it on Simulink but I didn't see any response on the Scope

I used discrete impulse as input What can I do to see the output ?

Thanks

I get this warning :

Warning: The model 'FIRFilterTest' does not have continuous states, hence using the solver 'VariableStepDiscrete' instead of solver 'ode45'. You can disable this diagnostic by explicitly specifying a discrete solver in the solver tab of the Configuration Parameters dialog, or setting 'Automatic solver parameter selection' diagnostic to 'none' in the Diagnostics tab of the Configuration Parameters dialog.

Which filter did you make? Low pass high pass? Depending on that take a signal which has a frequency lying in pass band of that filter and another frequency outside of it. And then take fft of output to see whether the frequency outside of the passband has been eliminated.
 

Your filter takes continuous time data. Chirp is from continuous library. Replase it with digital source or insert Zero-Order Hold unit at fiter input with 1/800 sample time.
